java.net.URI.scanIPv4Address is a private method, it is only called by
java.net.URI.takeIPv4Address and java.net.URI.parseIPv4Address, the
URISyntaxException("Malformed IPv4 address") is not necessary, returning -1
should be good. In one of our systems, we noticed the exception consumes ~0.3%
CPU.
Additional test:
- [x] make test TEST=jdk/java/net
